Believers! Fight against the unbelievers who live around you; and let them find in you sternness. Know that Allah is with the God-fearing. 123 When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice. 124 But to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 125 Do they not know that they are tried every year once or twice? Even then they do not repent and take heed. 126 And whenever a chapter is sent down, one of them looks at the other; “Is there someone watching you?” – and then they turn away; Allah has inverted their hearts because they are a people who do not understand. 127 There has come to you a Messenger of Allah from among yourselves, who is distressed by the losses you sustain, who is ardently desirous of your welfare and is tender and merciful to those that believe. 128 But if they turn away, [O Muhammad], say, "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne." 129
